I think it would be a healthy choice for her to lose weight
Losing weight is only a part of trying to keep from being diabetic. Yes, diet and exercise are the major parts of this. People don't realize how much a regular sleep schedule is almost as important. Sleeping too much or too little screws up the body's demand for energy that insulin provides by burning sugar calories.
Diabetes isn't just treating high blood sugar because your body isn't producing enough insulin. High cholesterol levels contribute to it too. The body may have plenty of insulin floating through the bloodstream but it and the sugar can't get inside of the red blood cells and travel to the muscles that need it to burn calories for energy because the red blood cells are coated in cholesterol.
Cholesterol also clogs up the tiny blood vessels (capillaries) in the back of your eyes (retinas), in your fingers & toes and the important ones inside your kidneys that help flush out toxins and spent red blood cells that did their jobs and ran out of iron (those are what make your pee yellow). The sugars crystallize and begin to damage the walls of the capillaries, they become brittle and cause small bleeders, restricting blood flow to these areas that contribute to blindness, circulatory damage including varicose veins or other clotting problems that can lead to heart attack and strokes, neuropathy (losing the feeling in your fingers and toes) and reduced or permanent kidney and urinary tract damage.
A balanced, diabetic-friendly diet doesn't have to mean a boring starvation diet. It's all about portion control and eating on a regular schedule, breaking your meals up into lots of small meals and getting away from one or two big meals a day that force your body to store energy instead of burning it up quickly.
First; No More Diet Soda. Not going into details but that causes more kidney damage than real soda.
Second; No More Soda at All. Sorry. Of if you do, limit it to one a day and drink it over lots of ice.
Third; No More Deep Fried Foods. No breading or batter-dipped food. It's just a way to glue starch to protein with grease. A light spiced flour coating on meat that is baked or broiled tastes just as good.
Fourth; Alcohol. This has always been a back n' forth debate. A drink or two a day can help or hurt depending on which study you read. No More Sweet Cocktails. If a drink has two or more liquors, it probably has way too many calories. Binge drinking also throws your sugar/insulin levels way off.
Last; Lots more moderate exercise. Find something fun to do that involves moving around - bowling, Frisbee or kick a ball around at the park but make sure you do it on a regular basis. Save training for running a marathon for later after you get to your goal weight.
Someone who has been told that they are pre-diabetic will probably develop diabetes unless they make lifestyle changes. People can improve their health with a 5% to 10% weight loss.
That said, *you* can't do this, only she can. You can ask her what she thinks, you can ask her how you can help, you can be encouraging and supportive. But you can't make her do this.
Eat right and exercise. There is not a person alive who should not exercise at least 3-4 times a week minimum unless you are a really old person preparing for death etc.
You already awarded Best Answer; good choice.
Here's an even better answer bc it spells the end of obesity and the PREVENTION of diabetes II.
Yes, the PREVENTION.
Because, it WILL happen without dietary changes.
Even more, it will likely occur in YOU should you live long enough.
So; you're BOTH at risk, and it's not either of your fault.
Read the book "Fat Chance " by Dr. Robert Lustig M.D. to understand why she is fat, why YOU are fat, how it's reversible and why I am so cocky.
I already did it.
The most important thing she can do is to understand why she overeats - what does food do for her emotionally?
Many very overweight people have had childhood trauma - sometimes emotional abuse, sometimes sexual abuse, sometimes physical abuse, and sometimes all three. If your girlfriend is someone who had a difficult childhood, losing weight will not be effective until she really understands what is going on emotionally.
Do you really *need* to ask if a 2l5lb human with diabetes should lose weight?
She is obese and is selfishly putting a strain on the health services with her health conditions caused by her own greed for food.
Be blunt and direct. Tell her to stop eating junk and to stop being lazy.
It is better to have diet planning, avoid fast food, deep fried foods etc. Which will help her lose weight as well, but there is an herbal thing if she is aiming for weight loss "beyond weight management tea" an organic blend will be cooperative
She should improve her health to increase her quality of life. Fitness and weight can be mutually exclusive.
She 'should' do whatever she wants. Losing excess fat would probably greatly improve her physical quality of life and likely help with health issues she has or could develop. Having been obese myself many years ago, I know what it's like to be very overweight and what it takes to lose it. I wouldn't want to go back to being that 'extra large' person EVER again.
As for your girlfriend, it's her choice. Nobody can make someone lose weight. They have to do it because they are ready to do it and want to do it. I was heavy for a number of years before I got sick of the reflection I saw looking back at me in the mirror, and decided to do something about it.
